Modify lysine, below, to show the predominant form at ph 7.

The pH 7, suggests neutral state, that is, no proton in the solution. Its composition is given in the attachment below.

At pH = 7, Lysine possess net charge of +1. The isoelectric point of lysine is 9.75. Thus, its shows +1 net charge, it is actually a fractional charge.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

indium, and thallium have three electrons i think
